What is the tph meaning in boiler?
Definition of the tph meaning in boiler
When a steam boiler is continuously operated for a long period of time, the amount of steam generated per hour is called the evaporation amount of this boiler, and is usually used in tons per hour (t/h or tph).
A steam boiler is a steam device that uses heated energy or other thermal energy that is converted by the combustion of a fuel to heat the feed water to obtain specified parameters (temperature, pressure) and quality. 1 tph meaning in boiler means that the boiler can produce 1 ton of steam per hour under standard operating conditions.
Introduction of the tph meaning in boiler
The tph meaning in boiler, also known as the output of the boiler, is the basic characteristic parameter of the boiler. Steam boiler is expressed by evaporation, and hot water boiler is expressed by heat supply. When the boiler runs continuously for a long time, the amount of steam produced per hour is called the evaporation capacity of this boiler. It is represented by the symbol "D", and is commonly used in tons/hour (t/h). When the hot water boiler runs continuously for a long time, under the rated return water temperature, pressure and rated circulating water volume, the effective heat quantity of the outlet water per hour is called the rated heat supply (output) of this boiler. Represented by the symbol "Q", and the unit is megawatt (MW). The hot water boiler generates 0.7MW(6×105kcal/h) heat, which is roughly equivalent to the heat of 1t/h steam generated by a steam boiler.
According to the tph meaning in boiler, boilers can be divided into small boilers, medium boilers and large boilers. There is no clear and fixed boundary in size division. Some people say that if the evaporation capacity is below 20t/h, it is regarded as a small boiler; if the evaporation capacity is between 20 and 75t/h, it is regarded as a medium boiler; if the evaporation capacity is above 75t/h, it is regarded as a large boiler.
How to choose the tph meaning in boiler
According to experience, the selection of small tph meaning in boiler can be determined in the following two ways:
1. Obtain the heat load curve and heat balance system diagram of heat users, and determine the design heat load after taking into account various heat losses, self-use heat of boiler room and available waste heat.
2. When there is no heat load curve and heat balance system diagram, the heat load can be determined according to the peak heat consumption of production, heating, ventilation, air conditioning and living hours, and after each heat loss and simultaneous use coefficient are respectively included, the self-use heat of the boiler room and the available waste heat can be used.
In addition, the number of newly built boiler rooms should not exceed 5, the total number of expanded and rebuilt boiler rooms should not exceed 7, and the number of non-independent boiler rooms should not exceed 4.
The single boiler capacity of ZOZEN Boiler covers 1-130t/h, meeting the heat demand of most enterprises. According to the actual working conditions, ZOZEN Boiler can provide one-stop boiler service. Welcome to consult online for more details on tph meaning in boiler.
